SIDE III - Symmetries and integrability of difference equations

Results not yet published elsewhere and overviews of various aspects are among the 42 papers by researchers from different disciplines who use discrete integrable systems, that is systems that can be described by ordinary or partial difference equations and can be solved using exact methods. The themes include Lie-type symmetries of differential- difference and difference-difference equations, integrable differential-difference equations, fully discrete integrable equations from multi-dimensional lattices to cellular automata, discrete geometry and integrability, and continuous and discrete PainlevT equations and related problems.
